CAR-COUPLING.

SPEQIPICATION forming part of Letters Patent No. 298,005, dated May 6,1884.

Application filed February 14, 1884. (1% model.)

To all whont it may concern..-

Be it known that I, FERDINAND F. L rz, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements inOar-Couplers, of which the following is a specification. Thisinventionhas relation to improvements in car-couplers; and it consists in theconstruction and novel arrangement of devices as will be hereinaftermore fully set forth, and particularly pointed out in the claimsappended. In the accompanying drawings, to which similar letters ofreference are made, indicating corresponding parts, Figure l isjarepresentation of a frontviewof my device. Fig. 2 is a view of a sideelevation of the same.

Fig. 3 'isa plan view, and Fig. 4 isa longitudinal central sectionalview.

In the said drawings, the letter A indicates the coupling link, havinganaperture near each end for the passage of the coupling-pin P, which hasits lower end beveled, as shown, and its upper end provided with 'acollar, to prevent the link from falling through the aperture of thedraw-head, and the opposite ends of the link may be also beveled ontheir flat and edge walls, as shownin Fig. 2.

B indicates the draw-head, which has its walls converging rearwardly,and the lower forward wall is provided with an incline, a, as shown.This draw-head is provided with a solid vertical back, L, having lateralextensions b, which pass through slots in-the side plates, J, as will behereinafter more fully set forth.

G indicates a block of wood or other suitable material, which issecuredupon thebaseplate M, and between the side plates, J J, by boltsand nuts or other suitable fastening devices.

F indicates a block of rubber or other suitable elastic material, whichis arranged upon These side plates, J, extend forward asufiicientdistance beyond the forward end of the rubber block F, and are providedwith slots for the passage of the projections on the back plate, L, ofthe draw-head. These plates are also provided at their forward ends withlateral rectangular loops 0, which are formed by first bending theirends outward and then rearward, after which they are firmly secured tothe said plates with vertically-interposed metal strip D, as shown, andare placed in such a position transversely over the slots d in theplates J that when the draw-head has been driven forward so as to pressthe forward endof the rubber block F beyondtheforward edges of thevertical strip D, the rubber will be relieved from furtherpressure andthe force taken up by the engagement of the proj ections b with the saidvertical strips secured to the side plates, J.

By the employment of the rubber or cushion F it will be seen thatconcussion will be greatly reduced when the cars are brought together incoupling. H represents an arm consisting of a flat bar of metal, whichtapers rearwardly, and is provided with an eye for the reception of theking-bolt. The forward end of this arm ex-' tends through a horizontalslot in the rear portion of the block G, is hooked, and secured in anaperture therein by means of a transverse bolt, I, extending through thesaid block and side plates, J. r

The coupling-pin aperture of the-draw-head is provided with a boss orcollar, N, and connected to the coupling-pin by means of a chain orrope, e, is a bar, 9, which I shall termthe pin-set.

In operation, when it is desired to couple a car, the pin is raised andthe set '9 interposed longitudinally between its collar and the drawheadboss. When the link is insertedjinto the mouth of the draw-head,one ofits beveled ends will engage the end of the pin and raise itsufficiently to let the set fall away, the weight of the pin beingsufficient to allow it to drop down when it reaches the aperture in thelink, and thereby effecting the coupling.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a ear-coupler, the combination, with the draw-head having thesolid back provided with the lateral extensions b, of the side plateshaving slots to receive the said extensions,and the cushion-block F,substantially as specified.

2. In a car-coupler, the combination, with the draw-head constructed asdescribed, having the lateral extensions b, of the side plates, J,having the slots (1, the vertical strips D, and cushion-blockL,substantially as specified.

3. The combination, with the draw-head constructed as described, of theblock G, pro vided with the arm H, to receive the kingbolt, thebase-plate M, side plates, J, having the forward loops, C, and slots d,the drawhead having the rear lateral extensions, 1), the vertical stripsD, elastic block F, and interspace E, substantially as specified.

4. The combination, with the draw head having the bossed pin-aperture,of the coupling-pin constructed as described, the pin-set, andcoupling-link, substantially as specified.

5. The combination, with the draw -head having its inner walls taperingrearwardly, and provided with the incline a, of the coupling-link A,having its fiat and edge walls beveled at their ends, the pin P, havingits lower end beveled, and the pin'set connected to the pin,substantially as specified.
